You are underway on course 120°T and can make 12 knots. The eye of a hurricane bears 150°T at 120 miles. The hurricane is on course 295° at 20 knots. What course should you steer at 12 knots to have the maximum CPA?

Question

You are underway on course 120&deg;T and can make 12 knots. The eye of a hurricane bears 150&deg;T at 120 miles. The hurricane is on course 295&deg; at 20 knots. What course should you steer at 12 knots to have the maximum CPA?

Accepted Answer

Option C: 348&deg;. Per Bowditch hurricane evasion methods, plotting the relative movement vector triangle using own ship speed of 12 knots and storm vector 295T at 20 knots determines that steering course 348T achieves the maximum possible closest point of approach (CPA).
